sd-device.h provides an API to introspect and enumerate devices on the local
    system. It provides a programmatic interface to the database of devices and their properties mananaged by
    systemd-udevd.service(8).
    This API is a replacement for
    libudev(3) and
    libudev.h.

These APIs are implemented as a shared
  library, which can be compiled and linked to with the
  libsystemd pkg-config(1)
  file.
